Introduction to Numbers

AWK has numbers as most of the procedural computer languages do.
However all numbers in awk are stored as double precission floating point
numbers; no _integer_, _long_ or _float_ number types exist.
All values, literals or variables, are of type string or double
precission floating point numbers. So if you write:

  x = 5
  y = 5 / 2

the value of `y` is 2.5, not 2 as, e.g. it would be in C. Also the value
of x, internally, is 5.0, because, as we said above, all numbers in awk
are stored in double precission floating point numbers.
